Spin-orbital Conversion of Bessel Light Beams By Liquid Crystal Elements

KnE Energy / VII International Conference on Photonics and Information Optics (PhIO) / Pages 241–248

Abstract

For the first time, the spin-orbital conversion of the linearly polarized Bessel beams in the process of their propagation in the electrically-controlled liquid crystal cell has been realized experimentally. Variations in the polarization, phase, and spatial structure of the beam have been analyzed. It has been shown that, when a Bessel beam is propagating along the liquid crystal director, the generated beam is orthogonally polarized, whereas the topological charge is varied by two unities.


Keywords: Bessel light beams, spin-orbital conversion; liquid crystals
